Application iiled May 26, 1904. Serial No. 209,871.

To @ZZ whom, it wbr/ty concern:

Be it known that I, GARDNER P. COPP, a citizen of the United States,residing at Stockton, in the county of San J oaquin and State ofCalifornia, have invented certain new and useful Improvements inCouplings for Brush- I-Ieads 3 and I do declare the following to be afull, clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in couplings for brush-heads g andit consists in the effective and simple construction hereinafter setforth.

My object is to produce a fountain-brush particularly adapted for use inthe cleansing of buggies, though applicable for other purposes ingeneral. This object I obtain by the peculiar construction and relativearrangements of parts herein fully specified, and particularly pointedout in the claim appended.

Referring now to the drawings, Figure l represents a sectional view ofmy improved coupling applied to a fountain-brush. Fig. 2 is a sideelevation of my improved coupler detached from the brush and onanenlarged scale.

Similar numerals of reference indicate corresponding parts in bothviews.

1 designates the handle of a brush adapted to receive my improvedcoupler, which handle is made, preferably, of wood. Said handle has anenlargement or head 2 at its lower end, in which enlargement aresuitably embedded the bristles 3.

Inside the handle l is a chamber 4:, extending downward to about the topof the enlargement 2. A plurality of vents 5, running at any desiredangle through the enlargement 2, lead from the bottom of the chamber 4to the bottom of the said enlargement 2.

6 is a female coupling provided with a reduced end member 7. Said member7 has two or more iianges 8 on its lateral face and is also providedwith corrugations or bitingteeth 9.

In the making of my improved device the member 7 is pressed down intothe chamber 4, and the flanges 8 and the teeth 9, engaging with thewooden sides thereof, hold said member securely fastened in saidchamber.

I have now entered into a detailed description of the construction andrelative arrangement of parts embraced in the present and preferredembodiment of the same. I do not desire, however, to be understood asconfining myself to such specific details, as such changes andmodifications may be made in practice as fairly fall within the scope ofmy claim.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is-- A coupling for brush-heads,comprising an elongated tubular male member provided on opposite sideswith elongated longitudinallydisposed flanges, and on other oppositesides with transversely-disposed corrugations, and having an annularoutwardly extending iiange on its outer end, and a female member havingan inturned iiange at its lower end to engage with the flange on themale member, and having interior threads, as and for the purposedescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GARDNER P. COPP.
